Simple Modal

m.mount modal

This is another Modal component based on Vanilla CSS and some very simple Mithril.js code. The modal text is injected her, so the example is quite flexible even though it's so simple. Of course, for a real use case it has to be expanded slightly.

Live Example #

JavaScript #

let showmodal = false

const Modal = {
  view: v => [
    m('div.modal',
      m('div.c1',
        m('div.c2', v.attrs.text),
        m('button', {onclick: () => showmodal = false}, "OK")
      )
    )
  ]
}

const App = {
  view: () => [
    m('h1', "TEST"),
    m('button', {onclick: () => showmodal = true}, "show modal"),
    showmodal && m(Modal, {text: "This is a modal"})
  ]
}

m.mount(document.body, App)

CSS #

.modal {
  position: fixed;
  top: 0;
  left: 0;
  width: 100vw;
  height: 100vh;
  background: rgba(0,0,0,0.8);
  display: flex;
  justify-content: center;
  align-items: center;
}

.c1 {
  text-align: center;
  padding-bottom: 40px;
  width: 200px;
  height: 100px;
  background: white
}

.c2 {
  padding-top: 40px;
  margin-bottom: 20px
}

The snippet is using the most current version of Mithril.js framework. It is aimed at beginners and shows some basic recipes.

In addition to the Mithril.js hyperscript function m(), here we can see an example of Mithril.js' m.mount API method.
